Trimethyl citrate can be synthesized through the esterification of citric acid with methanol. Here’s a step-by-step guide to the synthesis:
### Materials Needed
1. **Citric Acid** (C6H8O7)
2. **Methanol** (CH3OH)
3. **Acid Catalyst** (e.g., sulfuric acid or p-toluenesulfonic acid)
4. **Reflux apparatus** (including a reflux condenser)
5. **Separatory funnel**
6. **Rotary evaporator** (optional)
7. **Ice bath**
8. **Distillation apparatus**
